How to tell if tinyMCE has been initated?

Question

I initiate the tinyMCE like this in multiple tabs of JQuery:Tab. But I find to init tinyMCE multiple times yields readonly text areas. Thus I wish to check if tinyMCE is already initated. Is there a method like isInitated() or something similarly convenient there?

tinyMCE.init({
    mode : "textareas",
    theme : "simple",
    width : "500",
    height : "300"
});

Answer 1

You can use tinymce.editors.length to see if there is already an editor instance initalized (tinymce.editors.length > 0).

Answer 2

I know this question is old, but...in case someone is still looking for the holy grail:

in tinymce 4, you can pass a callback to tinyMCE.init like so:

tinyMCE.init({
  //your regular parameters here...
  setup: function(editor) {
    editor.on('init', function() {
      //all your after init logics here.
    });
  }
});
